DOYANG — India

Hydro power plant in Nagaland, India. Approximate location 26.2325, 94.2612.

HydroNagalandIndiaconventional storage

DOYANG is a 75 MW hydro power plant in Nagaland, India. It is operated by North Eastern Electric Power Corporation LTD (NEEPCO) [100%]. Based on reported annual generation of 230 GWh, it can supply roughly 66k homes. It ranks #941 of 2,225 India power plants by installed capacity. Commissioned in 2000, it is around 26 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 8.6% of India's electricity; the national grid averages 670 gCO₂/kWh (26.7% low-carbon) (2025).

In context: how this plant compares

At 75 MW, DOYANG is around the median hydro plant in India (80 MW). Technically it is described as conventional storage. Hydropower converts the energy of falling or flowing water into electricity; output depends on rainfall and reservoir level, and large dams also provide grid balancing and storage.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a humid subtropical (dry winter) climate (Köppen Cwa) — Northern Hemisphere, latitude 26.2°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 88% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 18/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.

Site climate & environmental severity

This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.
